Note also a difficulty with this translation. The present/non-past form of the verb 食べる does not refer to a continuous, ongoing state such as eating, but to the future or to an action carried out on a regular basis. You can use the てーいる conjugation （食べている = now eating） to describe the English progressive tense of is-ing.
And just FYI, much more common kanji for sushi are 寿司 (not phonetic equivalent) or 鮨。:gohan:
